Change in osmo-msc[master]: propagate Compl L3 Info Cell ID to the VLR subscriber record

[laforge]

laforge has submitted this change. ( https://gerrit.osmocom.org/c/osmo-msc/+/18997 )

Change subject: propagate Compl L3 Info Cell ID to the VLR subscriber record
......................................................................

propagate Compl L3 Info Cell ID to the VLR subscriber record

As soon as the subscriber is authenticated, update the VLR entry with the
MSC-A's full CGI, including the Cell Id received from the Complete Layer 3
Information.

Thus the Cell Id will be shown by vty 'show subscriber cache' and 'show
connection'.

This is tested by osmo-ttcn3-hacks Ie410714a96353f74a52a104c56fa0a08683e0004.
